The NYPD is asking the public to help to identify two Subway creeps – including a pervert who masturbated in front of a 13-year-old girl on the 1 train last month.

Cops are also looking for a man who forcibly grabbed a 26-year-old woman’s breasts Friday afternoon on the southbound N train as it was heading toward the Kings Highway station in Brooklyn, cops said.

The lewd 1 train incident happened on March 7 at about 4 p.m., the NYPD said. The suspect exposed himself to the teen girl while the train was headed northbound in the vicinity of 137^th Street and City College subway stations in Manhattan, cops said.

Cops asked anyone with information on the incidents to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS or log onto the CrimeStoppers website.
